Vertical pressure steam sterilizer use method and precautions

Traditional sterilizers, also known as steam sterilizers, can be divided into portable sterilizers and vertical autoclaves. As various precision instruments and equipment are gradually being applied, these devices are often unable to withstand high temperatures and cannot be autoclaved. In order to solve this problem, various low temperature sterilizers are gradually produced. A conventional sterilizer uses a heating wire to heat water to generate steam and maintain a certain pressure. There is mainly a barrel that can be sealed, a pressure gauge, an exhaust valve, a safety valve, and a heating wire.

How to use the sterilizer:

1 Add an appropriate amount of water to the outer pot, place the items to be sterilized into the inner pot, cover the lid and twist the screw symmetrically.

2 Heating causes steam to be generated in the pot. When the gauge pointer reaches 33.78 kPa, the exhaust valve is opened to discharge the cold air. At this time, the gauge pointer drops. When the pointer drops to zero, the exhaust valve is closed. 3 continue to heat, the steam in the pot increases, the gauge pointer rises again, when the pressure in the pot increases to the required pressure, the firepower is reduced, according to the characteristics of the sterilized items, the vapor pressure is maintained at the required pressure for a certain time, then Power off or ignite the sterilizer, let it cool naturally, then slowly open the exhaust valve to remove the residual gas before opening the cover.

Sterilizer notes:

a should not be too tight to place the items to be sterilized

b The cold air must be completely excluded, otherwise the temperature in the pot will not reach the specified temperature, which will affect the sterilization effect.

c After sterilization, do not deflate and decompress, otherwise the liquid in the bottle will violently boil, flushing the stopper and overflowing or even causing the container to burst. It is necessary to open the lid after the pressure in the sterilizer has fallen to the same level as the atmospheric pressure.

d Now there is a high-pressure steam sterilizer automatically controlled by the microcomputer. After the air conditioner is placed, the instrument can automatically press the constant voltage. When the time is up, the power is automatically cut off and the whistle is uttered, which is convenient to use.
